The battery is made in a rigid frame steel casing. The lower part of the structure is filled with steel ballast. At the top are lithium iron phosphate elements, as well as CPS, outside is covered with sheet steel to protect against external influences. The batteries are equipped with an electronic control system and protection against overcharging, overheating and other abnormal operating modes and retain its parameters after the impact of mechanical factors corresponding to the M2 operating group in accordance with GOST 17516.1-90. To store energy in the battery, lithium-iron phosphate (LiFePO4) elements are used. The design of the batteries ensures the inaccessibility of touching current-carrying parts, including in the open for maintenance and repair, in accordance with GOST R IEC 60598-1-2011. The total charge time of the battery is no more than 2 hours. The design of the battery allows you to carry out a fractional charge cycle of any duration at any level of charge.
